This paper investigates the impact of conservative accounting and economic rents processes on residual income. We find that: (1)Residual income significantly increases with conservative accounting, firm size, and R&D intensity; residual income significantly decreases with the proportion of tradable shares and capital intensity; and residual income does not increase with marker share and AD intensity. It indicates that the enterprises can obtain certain Ricardo rent and Schumpeter rent through the expansion of firm size and increasing R&D investment, but improve the market share, and advertising inputs without obtaining these rents; even capital density increase leads to the loss of Chamberlain rent. (2)Accounting conservatism and R&D intensity, AD intensity, financial leverage have an interactive effect on residual income, but increase the market share and the proportion of tradable shares，capital density and firm size does have not a significant effect.
